I saw a post today where a guy asked about building 1 site with 3 themes or 3 sites with 1 theme. Which is better? Honestly I have been in this game for some time now and I have learned that it is much easier to manage fewer sites. And from an SEO standpoint it is easier on the pocket book. Right now Google does not see "sites". Google looks at your site as a grouping of individual pages. So if you have different themes for your site you will be ok. Look at all these shopping mall sites that offer everything under the sun. You don't see 500 different versions of outpost.com. This same principal can be applied to inbound links. As long as your page theme matches the theme of the page linking to you everything will carry full value. I know some believe that Google looks at site theme but everything points to pages.
I was referring to the fact that someone can have a website on beach rentals but if they place a page on cotton candy they can ranksit. Example... Look at all the blogspot blogs that rank for key terms. If Google knew that blogspot was only to contain "blog" related keywords you wouldn't have people ranking for air purifiers and the like. Same thing happens when people create super affiliate sites. You create 1 site with every topic in the owrld and try to rank all of it.

I think 3 sites with 1 theme. This way you can link them all together and create a "network". What I'd do is take the general theme and break it down. Example: Theme - lyrics Site1: Country Site2: Pop Site3: Rap From my view this would perform better in the long run.
